Description

A kind of device that is useful for indoor medium-sized shear test
Technical field:
The utility model relates to a kind of device that is useful for indoor medium-sized shear test, belongs to Geotechnical Engineering soil test technique field.
Background technology:
Shear test to manipulated soil mainly contains three kinds of test methods at present:
1, on-the-spot direct shear test;
2, indoor direct shear test, triaxial test;
3, the indoor middle scissor test of minority;
Shortcoming: on-the-spot direct shear test, to carry out the scene and fill that the experiment work amount is big, the test period is long, expense is high, its overall work efficiency is slow, complex procedures, artificial use amount is big, and security risk is big; Shop experiment is because volume of sample is little, and test findings is difficult to truly reflect the Shear Strength Index of the soil body, and scissor test equipment was outmoded during existing minority was indoor, and efficient is low, and precision has much room for improvement.
Summary of the invention:
The purpose of this utility model is to overcome the deficiency of prior art, and a kind of high efficiency, experimental data a kind of device that is useful for indoor medium-sized shear test reliably is provided.
The utility model is a kind of device that is useful for indoor medium-sized shear test, this device is by the rectangle counter-force support (1) that counter-force is provided, the horizontal pressue device of spiral (2) that closely contacts with reaction frame (1), place the proving ring (3) that the horizontal shear force size is read in survey that is used for of horizontal pressue device (2) one ends of spiral, one end closely contacts with proving ring (3), the other end and down cut box (5) closely contact by fixed support, the parts (4) of the measurement horizontal shift size that bearing and dial gauge constitute, place down cut box (5) and the last shear box (6) of the loading sample on the steel plate (10), place the lifting jack and the vertical pressue device of spiral (7) that are used for vertical loading that are equipped with tensimeter (8) on the shear box (6) its, place the row of rolling (9) that is used for reducing bottom friction power of steel plate (10) below, and steel plate (10) is formed.
The utility model adopts product and the material of market sale to prepare according to a conventional method.
Advantage of the present utility model is:
1, owing to adopt the reaction frame of making in advance to add counter-force, the pressure size can be pressed design setting, can test the sample with different shearings.
2, the spiral reinforcing is adopted in the level pressurization, and proving ring is surveyed and read pressure, has overcome the difficulty that level is installed lifting jack, has improved work efficiency.
3, level pressurization and the same reaction frame of vertical pressurization can improve measuring accuracy.
Description of drawings:
Fig. 1 is main TV structure synoptic diagram of the present utility model.
Fig. 2 is the structure vertical view of part of the present utility model.
Embodiment:
The utility model is a kind of device that is useful for indoor medium-sized shear test, this device is by the rectangle counter-force support 1 that counter-force is provided, with the reaction frame 1 tight horizontal pressue device 2 of spiral that contacts, place the proving ring 3 that the horizontal shear force size is read in survey that is used for of horizontal pressue device 2 one ends of spiral, one end closely contacts with proving ring 3, the other end and down cut box 5 closely contact by fixed support, the parts 4 of the measurement horizontal shift size that bearing and dial gauge constitute, place down cut box 5 and the last shear box 6 of the loading sample on the steel plate 10, place the lifting jack and the vertical pressue device 7 of spiral that are used for vertical loading that are equipped with tensimeter 8 on the shear box 6 its, place the row of rolling 9 and steel plate 10 compositions that are used for reducing bottom friction power of steel plate 10 belows.
The utility model adopts product and the material of market sale to prepare according to a conventional method.
Before the test, will put into shear box by the sample that designing requirement (manipulated soil being carried out index controls such as grating, water cut, packing) makes, use the pressing machine hydrostatic profile, by position shown in the accompanying drawing other parts will be installed again.
Principle of work of the present utility model is:
Provide counter-force by counter-force support 1, the vertical pressue device 7 of spiral is to trying the vertical load that body applies certain value, and the horizontal pressue device 2 of spiral applies horizontal shear force successively then.In the process of the test, vertical load is surveyed by tensimeter 8 and is read, and the horizontal shear force size is surveyed by proving ring 3 and read, and the horizontal shift size is measured by parts 4.Increase severely up to the shear box horizontal shift, after horizontal maximum shear stress appears in the examination body, horizontal shear force will descend, and think that then trying body has cut damage, and the shear test of this sample finishes, and every group of soil body will be made 4 samples.
Show that through the reality use the utility model reaches designing requirement fully.
